Nuclear Energy in South Africa

This report by the South African Institute of International Affairs examines South Africa's transition from a secret apartheid-era nuclear weapons programme to a state committed to nuclear non-proliferation and the peaceful use of nuclear energy. It details the country's normative frameworks, governance structures, and the challenges facing its nuclear energy expansion plans, including the legacy of state capture during the Zuma presidency and the current cautious approach under President Cyril Ramaphosa.

• South Africa transitioned from a secret nuclear weapons programme, which produced six devices between 1978 and 1989, to becoming a global advocate for nuclear disarmament and non-proliferation after the IAEA verified the programme's complete dismantlement in 1993.
• The country has established a comprehensive normative framework by ratifying numerous international treaties, including the NPT in 1991, and joining export control regimes such as the Nuclear Suppliers Group (NSG) and the Missile Technology Control Regime (MTCR).
• Nuclear governance is managed by the Department of Mineral Resources and Energy (DMRE), which oversees entities including the National Nuclear Regulator (NNR), the Nuclear Energy Corporation of South Africa (NECSA), and the National Radioactive Waste Disposal Institute (NRWDI).
• South Africa possesses significant uranium reserves, ranking fifth globally, though production decreased by 32.5% between 2016 and 2017 due to an oversupplied market and lower gold production.
• The Koeberg Nuclear Power Plant, which provides approximately 6% of the country's electricity, is reaching its 40-year design life in 2024, with plans under the Integrated Resource Plan 2019 to extend its operation until 2044.
• The nuclear energy expansion plans under President Jacob Zuma were characterized by a lack of transparency and were later identified as a facade for large-scale state capture, leading to unconstitutional agreements with vendor countries like Russia.
• Under President Cyril Ramaphosa, South Africa has adopted a more cautious nuclear build approach via the IRP 2019, aiming to procure 2,500MW of nuclear energy by 2024 using smaller units rather than a large fleet.
• The nuclear sector faces critical challenges, including fragmented governance across multiple ministries, a dwindling pool of technical expertise, and severe budget constraints for nuclear energy regulation and management.
• NECSA has suffered from severe financial and governance failures, becoming 'technically bankrupt' and experiencing a shutdown of its NTP radioisotope plant in 2017 due to safety lapses.
• South Africa's reputation as a non-proliferation leader was damaged by the involvement of private entities in the global nuclear proliferation network of Pakistani scientist AQ Khan, which operated until 2004.
